No problem! Anytime one came up, I was pinging anyone in the steam friends list who was online. I managed to snag all 5 this weekend, so I'm up to 9...getting harder and harder to wait until 50 to use them.

I found out I could use IFTTT.com (if this then that) to send me a text to my google voice whenever they post a shift code to twitter. It could also be configured to send an email, or whatever. I have no idea how many I've missed (its been a lot since I've gotten ZERO from that), but never again.Edit: If you do this, you have to use the RSS feed to trigger from.
